maintenance-pass skillA
maintenance-pass is agent-read markdown (skill) from uchicago-dsi/ai-sci-skills: Run safe, high-yield codebase maintenance passes that trim dead code, vestiges, duplicate implementations, stale scripts/configs, and excessive LOC without churn. Use when the agent is asked for a maintenance pass, cleanup pass, code cleanup, slop trimming, dead-code removal, de-duplication, vestige pruning, or refactors whose purpose is reducing maintenance burden rather than adding features..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Maintenance Pass ## Optimize For Maintenance Yield Prioritize the safest change with the largest maintenance payoff. Delete or simplify code only when evidence supports it. Refactor only when it materially reduces duplication, clarifies ownership, removes a failed path, or protects an important contract. Do not move code around for aesthetics. Use this rough ranking: ```text maintenance yield = impact * confidence * stale_touch_signal / blast_radius ``` Treat time since last git touch as a triage signal, not proof. The relevant metric is the most recent commit that changed a path, not when the file was created. Code whose latest git touch was a long time ago is more likely to be a vestige, duplicated old path, or stale interface, but stable core infrastructure can also be old and correct. ## Start With Evidence 1. Read local repo instructions first: `AGENTS.md`, `CLAUDE.md`, `README.md`, nearby runbooks, and provenance notes tied to the target area. 2. Check the worktree: `git status --short --untracked-files=all`. Never revert unrelated user changes. Avoid destructive cleanup in a dirty worktree unless the user explicitly scopes it. 3. Establish stable baselines: …

How to install
mdr add uchicago-dsi/ai-sci-skills/maintenance-pass@git:20260921.9b3de7cmdr add uchicago-dsi/ai-sci-skills/maintenance-pass@sha256:283fd73840814534Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
